fix(lint): ignore proxy-label tween overlaps

[miguel-heygen]

Summary

• stop treating parser role labels such as dwell/hold and proxy → … as stable target identities
• avoid false overlapping_gsap_tweens findings for simultaneous drivers on distinct object proxies
• retain overlap detection for resolved DOM targets

Reproduction

Confirmed on hyperframes@0.7.56: two distinct proxy objects, each tweening value from 0–2s with ease: "none", both collapse to the dwell/hold parser label and lint reports a phantom self-overlap.

Verification

• bun test packages/lint/src/rules/gsap.test.ts (86 passed)
• bun run --cwd packages/lint typecheck
• bunx oxfmt --check packages/lint/src/rules/gsap.ts packages/lint/src/rules/gsap.test.ts
• bunx oxlint packages/lint/src/rules/gsap.ts packages/lint/src/rules/gsap.test.ts
• git diff --check

The repository-wide pre-commit typecheck was attempted but a fresh worktree lacks generated packages/core/src/generated/runtime-inline modules; fallow also evaluated unrelated baseline changes against origin/main. Targeted lint tests, package typecheck, formatting, and lint all pass.

Human review required; do not self-merge.

Superseded by #2413, which consolidates this regression with the related lint/audit correctness fixes, preserves the unique coverage, and is green across all required CI.
